66-252 50 x 50 mm N-BK7 45 deg Reflective Yellow Dichroic Filter; t=4 mm 400-725nm

The 66-252 is a 50 x 50 mm N-BK7 45 degree reflective yellow dichroic filter with a thickness of 4 mm, designed for use within the wavelength range of 400-725nm. This filter, sourced from the renowned optical components vendor Edmund Optics, is a high-quality, rectangular dichroic filter, featuring a yellow coating on both the front and back surfaces.

The filter's primary function is to selectively reflect or transmit specific wavelengths of light while maintaining high optical efficiency. In this case, the 66-252 filter features a cut-on wavelength of 520nm and is designed to reflect the yellow component of the spectrum at a 45-degree angle. This characteristic makes it an ideal choice for applications that demand precise wavelength discrimination and color separation.

The N-BK7 substrate material, a high-quality borosilicate glass from Schott, ensures excellent optical performance and maintains low auto-fluorescence levels. The 4 mm thickness of the filter provides improved durability and rigidity, making it suitable for various optical systems and setups.
